Invisible Ink Created From Engineered Bacteria

September 26, 2011 Leave a comment Go to comments

“By seeding sheets of what look like paper with encrypted patterns of bacteria engineered to glow in certain conditions, researchers have developed an invisible ink for the biotech age.

Among the potential uses are secret, forgery-resistant bacterial barcodes and watermarks, though imagination soon arrives at more entertaining possibilities.

“Obviously, the secret agent kind of application jumps out,” said chemist David Walt of Tufts University, who developed the system with fellow Tufts chemist Manuel Palacios. “Somebody embedded in an environment where they need to get a message out but don’t want to be caught.”

The system, which Walt and Palacios named InfoBiology — individual messages are called SPAM, short for “Steganography by Printed Arrays of Microbes” — is described Sept. 26 in Proceedings of the National Academy of Sciences. It builds on principles displayed in Walt’s earlier work on fuses that convey information as they burn, producing a simple form of chemistry-based communication.”

    Wow, and here I thought invisible ink can only be seen on TV and spy movies.
